1- You use solution 'on the fly' only if you have one or few images?
But that's advantage to use gd with imagemagick, respect to use only
the second?

2- This is another solution for to use both.
Which are the advantages?

3- For only resize images into a new directory to use after for web
gallery, you use only imagemagick?

For all 3 solutions, where have you look codes?
